I eat no sugar, I eat very healthy. In fact, over the past month I've gained more muscle mass, I'm more fit than ever. Not sure what happened really. It almost looks like it's full of air.
I'll do crunches and reverse crunches I guess.
Could be something not muscular related. Having gas, could make you bloated, over hydrating can make you bloated, even a backed up digestive system can make you bloated.
To the point that you "stomach" gets pushed out.
Is it flabby, or is it taut? (your belly I mean) like....if you push on it, does it have resistance, or can you stretch it easily.
